Hair-curling unit

HAIR-CURLING UNIT Filed Sept. 10, 1954 United States Patent l-Claim. reuse-4" s) My present invention is a novel and improved haircurling unit 'for home employment or self-use, and ineludes an improved method of manufacturing the same, and is an improvement on the hair-curling device of my prior Pat. No. 2,598,837 dated June 3, 1952.

In my development of the hair-curling art, I have discovered that a prepared heat-generating unit may be advantageously formed by combining relatively large sheets or layers united together by stitching or the like, and producing a combined sheet of thin aluminum protecting foil, a retaining gauze or other sheet, and an intermediate pre-treated textile material which has been dipped in a suitable chemical to constitute an exothermic material capable of generating heat upon moistening'. These sheets are prepared with an aluminum sheet of greater area and are then folded with the aluminum foil comgauze; and thereupon the thus-folded layers are cut transversely across the line of stitching and into separate units.

of appropriate size.

These units may thus be employed in any type of curler, although preferably as illustrated herein and as will be further described.

Thus my hair-curling unit provides a simple, efiicient, and speedy hair-curling operation, eliminating the necessity of prior methods of mixing, assembling the haircurling device with exothermic material, and eliminates also the necessity of hair clamps, curling rolls, protecting pads, and the like accessories.

My unit can also be conveniently packaged with curling strips, hair-setting solution, and the like and can be utilized with a slight application of moisture, water, or hairtreating solution, and the protecting aluminum foil enables the operator to eifect the hair-curling action after the application of moisture before the heat generated is objectionable or damaging to the hands or fingers of the user.

Other advantages, novel features, and combinations will be hereinafter more fully pointed out and claimed.

Referring to the drawings illustrated in diagrammatic form, my present invention relates to a hair-curling unit wherein:

Fig. 1 is a view of a completed set of units arranged to be readily detached for individual use;

Fig. 2 is a diagrammatic view illustrating the method of manufacturing shown on a reduced scale;

Fig. 3 is a perspective view of the completed units illustrated in Fig. 1;

Fig. 4 shows a method of assembling an individual unit with a hair-curling strip having a reinforcing wire or the like therein;

Fig. 5 illustrates a preliminary step of uniting the unit and the hair-curling strip;

Fig. 6 illustrates the hair being curled about the unit;

Fig. 7 illustrates the method of utilizing the unit and hair-curling strip so as to constitute its own scalp-protecting method of use;

Fig. 8 is illustrative generally of a hair-waving use of 2,756,756 Patented July 31, 1956 attachment to the unit and especially designed for long hair. 1

My improved method of manufacture is illustrated'in Figs. 1, 2, and 3, wherein a layer of paper, felt, or textile material 1, which has been dipped in any suitable standard type of chemical for generating heat when moistened, constitutes the exothermic layer, covered on one side by a sheet of gauze 2, or the like, and applied to the intermediate portion of a larger sheet of aluminum foil 3; thesethree layers being united'by a line of stitching .4- all constituting a heating element. The relative size of the layers 1 and 2 and the larger aluminum layer 3 issuch that the end portion of the aluminum layer may be folded over on top of the layers 1 and 2, which are stitched to the intermediate portion and, thus, the folded -'.alu-

minum completely covers the layers 1 and 2, as clearly.

shown in Fig. 3. t I

The illustration of Fig. 2 is on a different scale from that of Figs. 1 and 3, as will be appreciated. With the folded structure thus prepared, it is then cut transversely approximately along the lines 6--6 crosswise of the stitching 4, thus forming a series of separate units 10-10, see Fig. 1; wherein the aluminum foil 3 completely covers the outer surfaces of the layers 1 and 2, protecting the same as well as protecting the hair and scalp of the user, as well as cooperating in the heat-generating action when the unit is moistened.

As thus formed, my unit may have the transverse cuts 6 completely thru, or partly thru, as illustrated in Fig. 1, thus leaving a small connecting margin, as indicated at 12, which permits the individual units 10 to be quickly severed therefrom. All such units may be completely severed and packaged in any number, size, and quantity desired for commercial use.

As shown in Fig. 4, I prefer to utilize my novel unit 10 in connection with the curling strip 15, which may be of paper or any other-suitable material, having a reinforcing wire 16 thru the center as indicated in dotted lines. With the unit 10 applied to the intermediate length of the curling strip 15, I may apply a sheet of paper 17, folding the same around and thereupon giving the combined paper, unit, and reinforcing strip 15 one or more twists to unite the same as illustrated in Fig. 5; whereupon, the unit with this curling strip is ready for use and, as illustrated in Fig. 6, a tuft of hair is wrapped around the central part enclosing the unit 10, which latter may have been moistened by dipping one end into water or solution, or otherwise moistened, the tuft of hair 20 being wrapped therearound. Thereupon, one end of the strip 15 is folded up over the hair thus wrapped, as shown in Fig. 7; and the other end of the strip 15 is folded underneath and, preferably, on edge so as to automatically space the curl 20 from the scalp 21 of the user, as clearly shown in Fig. 7.

In Fig. 8, I have illustrated the method of waving hair which shows a tuft of hair 24 spirally wrapped around the curler and unit; whereupon the end of the curler 15 is turned upwardly, as shown in dotted lines at 25. This spiral curl would ordinarily be much tighter but is shown herein in loose form for clarity.

My novel compact and efficient unit, and the method of manufacturing the same from relatively large layers, as well as the novel and quick method of uniting such a unit to the curling strip, and the doubling of one end of the strip underneath the wrapped hair to protect the scalp of the user during the heat-generating and curling opera tion, all without clamps, rollers, pads, or other attachments are important and novel features of my present invention.

Ordinarily five to ten minutes is sufiicient for the exothermic material to heat and curl the hair, depending upon 'text-ure, .weigh-t, and'ty-pe of hair; whereupon the curler can be readily removed.

My assembled and prepared unit can be packaged separately and used as a refill in connection with the curling .st-rip asilliustrated, 0r inconnection withother typeset permanent curling and waving devices.

'To moisten :Ihe predetermined intermediate layer 1, it is'only necessary-to dip the end inwater tar-solution then complete the attachment to the hair-curling strip bythe rolling twist, capillary attraction drawing the. moi-sture i-n-to theexothermic-treatedlayer; thus giving a somewhat delayed time heat-generating action to permit theassembling with the curler and --wrapping the hair thereabou-t, which is a desirable' feature, eliminating the danger. of burning the hands: or. scalp during the-hairwrapping action.

I claim:

A-hain-curling-unit of the kind-described, comprising a'flat strip consisting in a preatreated absorbent layer capableof generating heat When moistened, a protecting gauze layer on one surface and an aluminum layer of greater length and width on the opposite surface, all

united-by stitching, said aluminum layer beingfoldecl over the first two layers and enclosing the same, all constituting a heating element in combination with a relatively long flat wire-reinforced layer, all said layers being suitable to be spirally twisted in association with a tuft of hair intermediate the ends of the reinforcing layer, said reinforced layer having an end portion adapted to be folded under the tuft of hair in edge-wise position to space the heating elementtrem the-head of the wearer to the widthwiseextent of said reiniorcing layer.
